Sites Southwest as the on-call provider of landscape architectural services to the Sandia National Laboratories ("SNL") generated a Centralized Irrigation Control System design (CICS) for the SNL campus. This system will enable irrigation of landscape plantings to be initiated, controlled and monitored from a single point PC based controller. The system resulted in the consolidation and rationalization of the existing irrigation system. The system consists of a central control unit (PC), and a series of satellite controllers and flow meters, which communicate directly with the PC. The system runs via telephone line and/or radio on specified bands.
